AUDIBLE ALARM OR INDICATION APPARATUS.

To all whom it may concern:

Be it known that we, GEORGE E. WASH- subjects of the King of Great Britain and Ireland, and residents of Manchester, in the county of Lancaster, England, have invented a certain new or Improved Audible Alarm or Indication Apparatus, (for which we have filed an application in Great Britain on June 20, 1918, Patent No. 120,182,) of which the following is a specification.

This invention relates to an improved device for use in ofiices and other places where it may-prove useful, of that type for giving an audible alarm at any predetermined times, mainly to' indicate that a certain act or acts should be performedby some person withinsound of the alarm, the act or acts to be performed being noted on a paper strip, card or other suitable medium. As examples it may be that some one is to be telephoned to at a particular time, that some appointment should be kept at the time, that some step in'a process of manufacture must be arrested or commenced at the time of the alarm; for automatically controlling time tables in schools and so on with an almost infinite number of acts which will-be readily understood. I

To the aforesaid end our'inventioncomprises improved means to indicate the character of the act to be done, intermediate ;-gearing connected with the clock mechanism for causing a movable arm separate from theclock mechanism at a predetermined time or times either to close anelec- "trio circuit and give an audible electrical alarm, or to givea mechanically operated audible alarm, means to allow'the arm to be setto the correct time of day at the initial stage and means for stopping the clock at the end of theday.

Our invention will be fully described with reference to the accompanying drawings which show byway of example an apparatus constructed in accordanc with our invention and in' which, V I

In all foregoing figures similar reference characters indicate corresponding parts.

In accordance with our invention weprovide a strip of cardboard, paper or other suitable medium a of any required length and width, marked at the side, as in the column b the time of the day from say 8 oclock a.'m. to 7 oclock p. m. inquarter hour or other sub-divisions. The bulk of the paper surface is for memoranda of the acts to be performed at predetermined times. One strip may be provided for every day and be suitably dated for noting calls in the future. This strip is held in position .by suitable clips 0 on the cover (1 of the apparatus. A package of strips a bearing daily dates may be held in position upon a wooden or other base e or holder removably secured to the cover or frame of the apparatus so that daily memoranda may be written in readiness to place on the cover of the appa ratus.

The apparatus with particular reference to Figs. 1 to 3 comprises a base f for supporting the operative mechanism which is inclosed by the removable cover (Z. The latter is graduated at g to correspond with the division of time on strip a and is further provided with a slot it through which projects the operating or indicating arm ihereinafter more particularly referred to. In addition the cover has holes j for the reception of metal pegs I: which can be placed in such compression spring. a. p v

supply of pegsmay bekept in holes m. The mechanism to be'now described is former-1? ing the arm a through the arc of a circle to close an electric circuit and soundtlie alarms The means comprise ordinaryv clockwork mechanismin case n, the main shaft 0 of 3 which drives through suitable gearynincluding a wheel 3 freely mounted upon a fixed shaft 19 which carries a i'riction disk 0",, pressed against the wheels of the gear train referred to by a second disk 2; controlled by i The disk t has semoved. aroundby the clock to: indicate the time of day. The arm 2' carriesa flexible arm 12 adapted to contactwiththe pegs It as the main arm 2' moves forwardand so complete a circuit in which is included the battary wand electric bell 0c. 3/ isv the hammer of the bell. The various parts of thealarm mechanism are coupled by wires 2, to complete the circuit. The bell rings continuously while the flexible arm 2; passes the first peg 7c, the indicating-arm meanwhile passing forward toward. any other succeeding peg is. When the fieXible-arm clears the first-peg the-bell ceases to ring. =The flexible arm may .be replaced byaweighted arm or tumbler catch carried by arm-i.

contact with and lift a spring or pivoted arm 4 into the path of an arm 5 carried by the rotating olockshaft 6.

"In Figs. 5 and fi, we .haveshown mechania. cal means of giving an audible alarm. Heren we employ in connect on w th arm .i and carriedby it in a bearing-7 a rod 8 fitted with ashoe 9., The innerendof thearm is coupled to the pivoted striking arm 10 connected with a special gong or hell 11. A spring 12 normally presses-rod 8 'outwardly so that whenthe shoe 9 contacts with. pegs is the gong or bell isstruck-andan audible alarm given. 7 i r 7 Figs. 7 and 8 show a somewhat similar arrangement to that in Figs. 5 and 6' in which theinner endof rod 8 is arranged to strike a. bell 11 carried by the arm v Figs. 9 and 10 indicate a modificationof the. arrangement shown in Figs. 7 i and .8 in

which the rodS is turned about its axis when contacting pegs late strike the-gongll.

of the indicating arm i, provided witha tip 13' made of colored fiber or like material and incidentally to form a conspicuous indicator. The tip would be made to simply to eliminate the possibility of damage.

Fig. 14, shows a still further modification of contact device for the arm 2'. r This arrangement is designed to break, the circuit while wire is still against the eg 0 and so prevent wastage by bell ringing or an unduly long period. Itconsists ofa spring contact bar 15 insulated from thearm iat 16mak1ng .contact only-'atflpoint 1T, 18' is the wire to make-contact with peg 7c andfbeing in the form of a: sp1ral'spr1ng will make contact and ring thebell. The forward movement of thearm i will separate the points at 1'4 and break the circuit? Plate 19 will restrain the movement of thebar 15 and eventually cause wire 18 to slipofl'lthe peg 7c. 7 V

Fig. 18 shows; a fiat "type of -mach1ne in which the controlling mechanism is the same as inthat already described. "Theprincipal difference is that means areprovided to give av straight path to the indicating ar m which primarily to insulate the end ot the arm 'i pushtightly onto the arm 6 and may or may not be fitted with acushion spring 1 1 so as consists of a short arm 20 passing through the Set h, h mi freely mounted :upon a pin 21- supported' upon anextension The arm 2Q 1s counter.-

The indicating arm 1; may likewise be arranged to automaticaly break the electical circuit on the arm reaching the end of the slot h and so prevent possibility of leakage when the machine is not in use. The tip of the arm 71 may also be a little below-the surface of the machine cover and the slot h shaft and projecting through the said slot,

means for sounding an audible alarm when the arm arrives at predetermined markings on the time card, and a clockwork mecha nism secured to the base and operatively connected with the said arm.

2.'In an audible alarm, a base, a cover plate secured to the base and provided with a slot and a row of holes arranged adj acent to the slot, a shaft secured to the base and arranged under'the cover plate, an osci1la tory arm pivoted on the said shaft and'projecting through the said slot, removable pegs inserted in the said holes, a flexible contact member attached to the said arm and engaging with the pegs one after another, means for sounding an audible alarm when the said contact member is in engagement With any one of the said pegs, and a clock work mechanism secured to the base and 0p eratively connected with the said arm.

3. In an audible alarm, a base, a cover plate secured to the base and provided with a slot, a shaft secured to the base and arran ed under the cover late a drivin Wheel journaled on the said shaft, a clockwork mechanism secured to the base and operating to revolve the said Wheel, a disk journaled on the said shaft, an arm secured to the said disk and projecting through the said slot, a friction disk interposed between the said disk and wheel, and a spring holding the friction disk in driving engagement with the said disk and wheel and permitting the said arm to be moved back and forth by hand in the slot to set it.

In testimony whereof we have hereunto set our hands in the presence of two witnesses.
